Answer:
w^2+9w+20
Step-by-step explanation:
Apply the FOIL METHOD: (a + b) (c + d) = ac + ad + bc + bd
a = 5
b = w
c = w
d = 4
= 5w + 5 x 4 + ww + w x 4
= 5w + 5 x 4 + ww + 4w
Simplify 5w + 5 x 4 + ww + 4w:
w^2 + 9w + 20

Find x,
45x - 15x = 300
Answer:
x = 10
Step-by-step explanation:
45x - 15x = 300
Combine like terms
30x = 300
Divide each side by 30
30x/30 = 300/30
x = 10
Please help me with this and please explain how you found your answer.
Find 25% of 30.
A. 32
B. 3.25
C. 32.5
D. 325
Answer:
Huh, the answer option doesn't exist. The answer is 7.5 You can double check my answer by multiplying 7.5*4 because 25% is 1/4th of 100%.
Step-by-step explanation:
Use cross multiplication. I've heard it being called butterfly multiplication. I'll try to represent it as best as I can.
x 25
---- = --------
30 100
You multiply 30 by 25 and x by 100
x*100=30*25
Then solve for x
x*100=750
x=750/100
x=7.5
Hope this helps :)

Allen needs to prepare a compound for the patient to pick up tomorrow. He needs to mix of drug A, with of drug B and of drug C. What is the total amount of the drugs mixed together? 2/5+5/3+9/3
Answer:
76/15
Step-by-step explanation:
Drug A=2/5
Drug B=5/3
Drug C=9/3
Add the drug combinations together
Drug A + B + C=2/5 + 5/3 + 9/3
The L.C.M of the denominators is 15
=6+25+45/15
=76/15
Or
=5 1/15
Allen needs to prepare 76/15 compound for the patient
3 + (5 + 7) Use the commutative property of operations to reverse the numbers in the expression. Use the associative property of operations to change the grouping after reversing the numbers in the expression. Evaluate the expression.
Answer:
commutative property:
A + B = B + A
So we have
3 + (5 + 7) = (5 + 7) + 3
Now distributive means that:
A + (B + C) = (A + B) + C
So (5 + 7) + 3 = 5 + (7 + 3)
now the equation is easier to solve, because 7 + 3 = 10
5 + (7 + 3) = 5 + 10 = 15
Answer:
Use the commutative property of operations to reverse the numbers in the expression.
✔ 3 + (7 + 5)
Use the associative property of operations to change the grouping after reversing the numbers in the expression.
✔ (3 + 7) + 5
Evaluate the expression.
✔ 15

iF J is between C and T, find the value of x and JT. CJ=8x+5, CT=55, and JT=4x+2
x=
JT=
Answer:
x = 4JT = 18Step-by-step explanation:
Given three points J, C and T on a line, if J is between C and T then;
CJ + JT = CT.
Given CJ=8x+5, CT=55, and JT=4x+2, substituting this parameters in the equation above will give;
[tex](8x+5)+(4x+2)= 55\\8x+4x+5+2 = 55\\12x+7 = 55\\12x = 55-7\\12x = 48\\ x = \frac{48}{12} \\x = 4[/tex]
SInce JT = 4x+2
[tex]JT = 4(4)+2\\JT = 16+2\\JT = 18[/tex]
Which of the following is not a property of zero?
If you divide any number by zero, the answer will be zero.
Zero is neither positive nor negative.
If you add zero to a number, the answer will be that same number.
If you multiply any number by zero, the answer will be zero.
Answer:
If you divide any number by zero, the answer will be zero.
Step-by-step explanation:
You can't divide by zero. If you divide an number by zero on a calculator, it will come out as 'undefined'.
All other statements are true.
An integer that is positive is greater than zero, and a integer that is negative is less than zero. 0 is equal to 0, so it is neither positive or negative.
The sum of a number and zero will be that number. You are technically adding nothing.
[tex]4+0=4[/tex]
The product of any number and zero is zero. This is the "Multiplication Property of Zero".
[tex]4*0=0[/tex]
"If you divide any number by zero, the answer will be zero." should be the correct answer.
"If you divide any number by zero, the answer will be zero." should be the correct answer.
What is property of zero?
Addition property of zero:
The addition property of zero says that a number does not change when adding or subtracting zero from that number.
Multiplication property of zero:
The multiplication property of zero says that zero times any number is equal to zero.
Explanation for correct option:
If you divide any number by zero, the answer will be zero.
You can't divide by zero. If you divide an number by zero on a calculator, it will come out as 'undefined'.
All other statements are true.
Explanations for other options:
An integer that is positive is greater than zero, and a integer that is negative is less than zero. 0 is equal to 0, so it is neither positive or negative.

3 + 2x ≥ -4 solutions
Answer:
x ≥ -7/2
Step-by-step explanation:
3 + 2x ≥ -4
Subtract 3 from each side
3-3 + 2x ≥ -4-3
2x ≥ -7
Divide each side by 2
2x/2 ≥ -7/2
x ≥ -7/2
Steps to solve:
3 + 2x ≥ -4
~Subtract 3 to both sides
3 - 3 + 2x ≥ -4 - 3
~Simplify
2x ≥ -7
~Divide 2 to both sides
2x/2 ≥ -7/2
~Simplify
x ≥ -3.5

Ethan drew a scale drawing of a house. He used the scale 1 millimeter : 5 meters. The actual
length of the garage is 10 meters. How long is the garage in the drawing?
millimeters
Answer:
2 millimeters
Step-by-step explanation:
Ethan used the scale 1 millimeter : 5 meters.
This means that 1 millimeter in the drawing represents 5 meters in actual life.
The actual length of the garage is 10 meters. Therefore:
5 meters = 1 millimeter
=> 10 meters = (10 * 1) / 5 = 2 millimeters
The garage is 2 millimeters long in the drawing.
can anybody help me on this?
Answer:
length = 62.41 inches
Step-by-step explanation:
Using pythagoras theorem -
Let
a = hypotenuse
b = height
c = length
a^2 = b^2 +c^2
75^2 = 41.6^2 + c^2
Therefore,
75^2 - 41.6^2 = c^2
5625 - 1730.56 = c^2
389.44 = c^2
square root (389.44) = c
62.40544848 = c
Answer:
62 inches.
Step-by-step explanation:
We need to use the Pythagorean theorem to solve this problem. If the diagonal of the screen is 75 inches, and the height is 41.6 inches, then these values represent B and C. We need to find the value of A, the length of the TV. Since [tex]A^{2} + B^{2} = C^{2}[/tex], all we have to do is square 75, which gives us 5625then subtract the value of 41.6 squared (1730.56)and finally, take the square root of the number we are left with after subtracting [tex]B^{2}[/tex] , or 1730.56, from 5625, or [tex]C^{2}[/tex]
5625 - 1730.56 =3894.44
[tex]\sqrt{3894.44}[/tex] = 62.405

If J is between H and K and HJ = 4x+9, JK = 3x+3 and KH = 33. What is the value of HJ?
Answer:
Step-by-step explanation:
Assuming KH is a straight line with K and H being the beginning and the end of the line. If J is between H and K, it means that J is a point on line HK. Therefore, we can say that
HJ + JK= KH
If HJ = 4x + 9, JK = 3x + 3 and KH = 33, it means that
4x + 9 + 3x + 3 = 33
4x + 3x = 33 - (9 + 3)
7x = 21
Dividing both sides of the equation by 7, it becomes
x = 21/7 = 3
Therefore, HJ = 4 × 3 + 9 = 21
